The study is quantitative research with pre-experimental way while using one group pretest-posttest design of research. Moreover, a research sample is taken by the method of probability sampling which is kind of simple random sampling. A technique of data collecting uses to test and non-test (questioner). A technique of data analysis uses descriptive statistic and inferential statistic. The results of this study show that the average value of student’s abilities to understand the physic concept on pre-test which is representatively 43.72, while in the post-test it is 88.00 while in the post-test it is 88.00 with an average n-gain of 0.78. The study shows that blended learning application generally takes a great response of students, which stood on 64.48% of the average scores.

The research method used is descriptive correlative with the sampling technique using proportionate stratified random sampling. The research instrument is using a questionnaire of physics teacher for grade XII high school and the results of national exam the 2018/2019 academic years, by respondents consisting of 15 teachers and 692 students. Data analysis uses pearson product moment correlations. The results are showed that teacher performance has a linear correlation of student learning outcomes with a correlation value (r) of 0.533 or 53.33% and 46.67% determined by other factors such as: the hierarchical relationship between the head master by teachers and staff, who are not established yet. On the other hand, management of school organization is not optimal. The results of this study can be used as a basic for policy making for the Edu...

Six samples of stat ions A , B , C , D , E and F w ere used in the experiment.The geophone spacing used w as set 1 m and total length of each line was 23 m. The result show s posit ive significance (best fit ) of R2 that ranges from 0.80 to 0.90. The fk (frequency-wave number method) dispersion curves analysis confirmed that the soil structure invest igated is divided into three zones: (1) Unsaturated soil zone (clay soil), in w hich the layer is dominated by soil w ith typically alluvial clayey silt and sand. The Vp ranges from 240 m/s to 255 m/s at a depth of 2 to 8 m. (2) The intermediate zone (st iff soil), in w hich the layer is dominated by sand, silt , clayey sand, sandy clay and clay of low plast icity. This structure is interpreted as part ially saturated soil zone, the soil is typically very dense. It contains soft rock typically fi l...

In light of this, geo-electrical vertical electrical soundings (VES) technique and drilling tests from which in situ standard penetration tests (SPT-N) and particle size distribution (PSD) analysis on some selected samples were carried out. Additionally, accuracy assessment of the field measurements was carried out statistically using coverage factor and uncertainty analysis at 95% confidence level in justification of the relationship between the estimated depth of the cavity and the resistivity values. The results of VES and 2D resistivity imaging show that three layers are delineated. The weathered bedrock with resistivity of about 500 Ωm hosts the cavity which is air-filled at shallow depth and saturated with fluid or clay with low resistivity of about 127 Ωm at deeper depth. The SPT N-values obtained ranges between 0-5 and 10-20 corresponding to weak/unconsolidated zone and consolidated sediments, respectively. The SPT N-values from the boreholes drilled agreed with the inferred lithology units from electrical resistivity survey. The results of the PSD suggest that sand/gravel sediments with grain sizes more than 0.075 mm dominated the study area. A combination of both the geophysical and geotechnical data shows good agreement and their relevance in addressing subsurface problems.

The study characterized the subsurface structure to delineate soil structure for the geotechnical application. Cross-section modelling of the residual anomaly generated the Maluri Bouguer Anomaly model for test site. The 2D microgravity models produced the contour map, displaying the characterization due to density contrast in rock types while mapping the subsurface geological structure at different depths. Moreover, a synthetic model was initiated with the assumption of lateral distance on the left and right sides taken at 50 m and a depth of 60 m. The results of modeling confirmed that the soil and rock type composition on models test site, i.e: topsoil (1.1 g/cm3), soil (1.8 g/cm3), clay (1.63 g/cm3), gravel (2.0 g/cm3), sand (1.7 g/cm3), shale (2.40 g/cm3), sandstone (2.76 g/cm3) and limestone (2.9 g/cm3).
